Walter Isaacson's new biography of Elon Musk has made headlines for its now-disputed account of how Musk supposedly scuttled a Ukrainian drone attack by pulling the plug on the Starlink satellite internet service guiding the drones.

But the 688-page tome, for which Isaacson spent two years shadowing Musk, also fills in some other details about Musk's life and career that have garnered less attention. Here are some of the questions about the billionaire Tesla and SpaceX CEO that the book answers, or at least sheds light on - and which Musk has not disputed, at least so far.
